    you are running a kernel which is known to have both load and security problems, I would advise you upgrade as soon as possible

    DO THIS ENTIRELY AT YOUR OWN RISK

    edit /etc/yum.conf and remove kernel* from the exclude list,

    then run:

    yum update

    once that has completed it should have updated your kernel, so re-add kernel* to the exclude list in yum.conf and you should be fine. - Reboot and then cross your fingers!!

    There are plenty of threads on this board about kernel upgrades so if you get stuck do a search, otherwise seek professional help.

    I could be mistaken but that looks like a Kernel from Virtuozzo or simular VPS software. Are you on a VPS server? If so dont worrey as your hosting provider handles the kernel, its shared between all of the VPS's on a node.
